Cold atmospheric pressure plasmas (CAPPs) have emerged over the last decade as a new promising therapy to fight cancer. CAPPs' antitumor activity is primarily due to the delivery of reactive oxygen and nitrogen species (RONS), but the precise determination of the constituents linked to this anticancer process remains to be done. In the present study, using a micro-plasma jet produced in helium ...

We utilize a multiphase model, CON-AIR (Condensed Phase to Air Transfer Model), to show that the photochemistry of nitrate (NO−3 ) in and on ice and snow surfaces, specifically the quasi-liquid layer (QLL), can account for NOx volume fluxes, concentrations, and [NO]/[NO2] (γ=[NO]/[NO2]) measured just above the Arctic and coastal Antarctic snowpack. Maximum gas phase NOx volume fluxes, concentra...

OBJECTIVE To measure levels of salivary nitrite (NO2-) and to localize nitric oxide synthases (NOS) in the labial salivary glands (LSGs) of patients with Sjögren's syndrome (SS). METHODS NO2- was measured by the Griess reaction. LSGs were analyzed using NADPH-diaphorase histochemical and immunohistochemical studies to determine the constitutive NOS (neuronal [ncNOS] and endothelial [ecNOS]) a...

The toxicity of NO3- and NO2- to mammals has been widely publicized. However, the kinetic mechanism of inhibition of human muscle creatine kinase by NO3- and NO2- has not been explored. The kinetic theory of the substrate reaction during the modification of enzyme activity previously described by Tsou (Adv. Enzymol. Related Areas Mol. Biol. 1988, 61, 381-436) has been applied to a study of the ...

Introduction: Air pollutants and respiratory diseases have a significant relationship and cause major health problems. Low attention has been paid to the daily hospital admissions due to the presence of pollutants in desert cities such as Yazd city, Iran. Therefore, this study aimed to investigate the short-term relationship between air pollution and daily hospital admissions due to respiratory...

The work function variations of NO2 and H2S molecules on Pd-adsorbed ZnGa2O4(111) were calculated using first-principle calculations. For the bonding a nitrogen atom from single molecule to Pd atom, maximum change was +1.37 eV, for two +2.37 eV. adsorption, reduced ?0.90 eV ?1.82 sulfur atoms respectively. Thus, both H2S, increased with an increase in gas concentration, showing that Pd-decorate...

Aiming at NOx (NO 90%, NO2 10%) and SO2 in simulated vessel emissions, denitration desulfurization were studied through ozone oxidation combined with seawater as absorbent. Specifically, the different influencing factors of analyzed. The results indicated that efficiency NO can reach over 90% when molar ratio O3/NO is 1.2. Ozone washing same unit decrease temperature NO, avoid high decompositio...

OBJECTIVES There is evidence that outdoor workers exposed to high levels of air pollution exhibit airway inflammation and increased airway symptoms. We hypothesized that these workers would experience increased airway symptoms and decreased nasal mucociliary clearance associated with their exposure to air pollution. METHODS In total, 25 non-smoking commercial motorcyclists, aged 18-44 years, ...

To provide molecular toxicological evidences for exploring the mechanism of arsenicinduced neurotoxicity the accumulation of arsenic (As), the formation of 8-nitroguanine (8-NO2-G) were examined in brain tissue of mice exposed to arsenic. And the gene expressions of inducible NOS (iNOS), superoxide dismutase 1 (SOD1) and peroxiredoxin 2 (Prdx2) were also analyzed by GeneChip. In the result, the...

objective(s): the effects of curcuma longa (c. longa) and curcumin on total and differential wbc count and oxidant, antioxidant biomarkers, in rat model of asthma were evaluated. materials and methods: total and differential wbc count in the blood, no2, no3, mda, sod, cat and thiol levels in serum were examined in control, asthma, asthmatic rats treated with c. longa (0.75, 1.50, and 3.00 mg/ml...
